20 The MM plates offer a number of desirable features including a Teflon-lined spherical bearing to provide positive location of the strut shaft, spaced main plates to restore bump travel on lowered vehicles and, according to MM, the widest range of camber adjustment in the industry. A nice feature of these camber/caster plates is that they allowed independent adjustment of the camber and caster. Note the washer stack used to dial in travel versus hood clearance.
